To all whom it may concer/ai v Be it known that I, JOHN S. Luserna citi-y zen of the United States, residing at Reading,

in the county of Berks and State of Pennsyl- Vania, have invented certain new and useful 'Improvements in FrictionLClutches; and I 1 5 consists in certain improvements which will be fully disclosed in the following specifieaf tion and claims.,

\ In the accompanying drawings, Whichform part of this speciiicatioin-Figure' 1 repre- 20 scnts a vertical longitudinal section, partlyin elevation of a clutch embodying my invention. Fig. 2 a transverse section on line 2 2,

outerring detached. Fig. 6 .an end view of the expanding head or sleeve. Fig. 7 a transverse detail section on line 7, 7, Fig. 1`, show= ing the inner end of the head. Fig. 8 a like view on line 8, 8, Fig, 1, and Fig. Q a vertical longitudinal section partly'in elevation, show- ,imT a modiiication'of thedevice.

meral 1 indicates ashaft, 2 a baseorbody provided with a' hub 3 to receive a pulley, not

1 shown, .an annular seat 4, and onopposite sides are arms 5, 5, terminating lugs 6, 6.

The base is made in two parts separated lon-' gitudinally'so that .it can be applied to ashaft without disturbing its alinernena and the parts are securedvtogether on the shaft by- 5 0 againstrevolving-onthe shaft bya key 9.- T 1e plate 9 is provided with opposite bearing",A surfaces 13,114, 'and adjacent to the plate'Q- isf a supplemental plartel 15,v also parts -andsecured together on th" transversgbars '16v secured to thes' @replete ty bons 17, and-Samplers.

vided .with a bearing surface A18, and between the seat 4' and the bearing surface 13 a ring 19 of leather orother like substance or'material is inserted, and between the surfaces-14 and 18 a ring 20 of likern'at'erial is inserted to produce resistance to the bearingv surfaces revolving oneach other and forming an effective clutch. 15 which lengage the arms' 5 'and prevent the plate revolving on the shaft 1. To thel'ugs (i The plate 15 is 'provided with lugs PATENT oir-Fien.

are pivotally secured levers 21and 22h pins or bolts 23 and said levers are provide with adjustable screws-"24, 25 which rest upon thef -I bars 16, and each forms a fulerum for itslre- `spective lever to' force 'the friction membersv 'together and effectually lock them 'under pressure.

26 indicates a head or sleeve jongiitudinau., movable on the Shaft 1 and Secured thereto;

by a spline 27, and engaged by theleversZl, 22, each of which is provided With a laterally projecting pin 28, 29 on which are rollers 30,

31 which'bear upon the faces 32 and'33 re-. i

spectively of the head 26. The partof the head engaged by the levers is rectangular in cross section, and the faces 32 andare'f preferably curved as shown. On theinner end of the head is arectangular flange `34: and

at the opposite-end is a circular flange 35, adL

jacent to which. is aconcentric groove 35 'to f receive the inturned ends of a'. lever, not

shown, for movingthe head in rectons to operate the clutch'.

' In theoperation of the clutch, the inward Inovement ofthe head or'sleeve 26 forces the levers 21 and 22 in the ysame direction, andI 4the "pins 24, 254 pressingupon the bars 1 6 force the ringor Pilate 15 against the rin 20, od 2 is drawn towar the opposite' dij' 'ring .19, and effectueJ ly locks the base With its pulley, not shown, to the plates or nuern-V bers 9 and 15 and drive the pulley with the .shaft 1.

In Fig. 9, I have shown 'a modification ol' my invention ada ted for use on'the end of a shaft, and in. Whic the base 2 and the plates,

9'and15 are not separated transversely. The' levers 21 and 22 engage a sleeve 36 on a rod,

37, having a flange 38 which engages'a b'ar 39' .hearing 10". .The sleeve 36, is connected toit-y lio 10'5 [on Athe plate l9, and is provided with'v a ballA l against Imitation in any snimble manner, the l tween said plates, said plates and levers sind 22 ere nioveil and pressnie :tpi lied tothe Fletes 9 and .l5 sind funn en ei; I
